Application October 1, 1940, Serial messages I Y I I 14 Claims. (o1.1 14 210). My invention relates to the class of devices which are employed for weighing or hoisting an anchor and for casting or launching the same, and an objector my invention, among others, is to provide a device of this character'that may be readily operated at a distance therefrom, as from-the post of the helmsman, thereby enabling the operation to be performed without assist.- ance and without the necessity 'or liability of having handsand clothing spa'ttered andsoiled with water and mud thrown off from the .anchor in the operation of hoisting it. i

1 One "form of an anchor hoisting apparatus embodying my invention'and in the construction and use of which the-objects herein set out,

ered into the Water, partsbeing broken away to show construction.

FigureB is a bottom view with the anchor arm extended but with the outer end broken off and the sheave 23 being: omitted for the .sake of clearness. r

Figure 4 .is a view in section on .a plane denoted by the dotted line 4-4 oiFig. 2.

Figure 5 is a detail view on enlarged scale illustrating the latching mechanism for connecting the coupling arms with the cheek pieces.

In the accompanying drawing the numeral 5 denotes the line of the bow of aboat .and B the deck thereof. A deck plate .I is securely fastened to the deck in any suitable'mannerto provide for i the attachment thereto. and support of ahoisting mechanism. A hoisting arm 8 is secured to a journal 9 mcuntedin hearings Ill on the deck plate, the journal extending through a hole in :the arm and being pinned thereto. Cheek pieces .inthe deck plate and they .supportsheaves 13-7-14 between them to receive a hoisting :cable l5 to be more particularly hereinafter describedr The hoistingarm 8 is provided at its outer end with aa hood 16 housing a sheave i1 ior the-support of the cable at this end ofthe arm. A basin Hi *to receive the anchorwhen it is lowered to the deck is secured to the arm as is also a crotch positioned "to receive'the stock of the anchor when placed on the deck. r

' Coupling arms 20-are mounted onthe journal 9 on opposite sides of the cheek pieces I i, these arms-extending through openings inthe deck plate and having a sheave 2| rotatably supported between them. The outer ends of the arms extend into-a space between two supports 22 secured to and projecting downwardly from-the "of a cheek piece H and to engage a shoulderll at one end of the groove to couple the arms to the cheek pieces for a purpose to be hereinaiter described. A releasing wedge 28 is pivotally mounted at the outer end of each arm, preferably on ends of the pivotal support for the sheave 21, these wedges being movable into spaces between the springs and arms to disin any suitable position eng'a-gethe dogs from the grooves 26. The wedges are operated 'as by'means of a pull cord .29 secured at one end to wedge actuating arms 30 rigid with the wedges and extending to a point in proximity to the steering apparatus for operation by the 'helmsman. Thispull cord ex- "tends over a sheave 34 mounted a bracket 32 projecting downwardly from the under side of the deck plate at its outer end and as :shown in Figs.

, '1 and 2 of the drawing. The wedge'actuating 'theanchor 33 passes intothe hood lfiabout the sheave H therein, along the arms 8 under- --ne'ath and-in contactwith the sheave l3 and over three sheaves I4, as'ishown in Fig. 2. The cable then passes about the sheave Ztwand to a winch of any ordinary construction and located for manual or mechanicalzoperation. 1 a

. Toaoperate the mechanism let it be assumed .that "the parts are the positions shown in the grooves :28: to permit movement of the cheek pieces. constituting ahousing for theasheaves,

independently of the arms 20 as the anchor is raised. Thereupon the winch is started and the cable I is drawn in around the sheaves l'l--l3l4 and 23, the anchor being thus raised to the position shown in Fig. 2. The winch may now be reversely'rotated to move the anchor up and down, dousing it in the water to wash mud therefrom. The winch then being further operated to Wind the cable the anchor connection with the cable will contact with thehood. l6 and being prevented, by reason of size; from entering the opening in the hood the arm 8 is raised to a vertical position from which it may mov downwardly under the action of gravity to 'a ing arm, along said arm in proximity thereto and about said cable supports to raise the outer end of said arm when extended to drop the supported in archedarrangement to receive said Y .cable and provide leverage in proximity to the the basin l8 with its stockin the crotch i9, rota tion of the winch being continued to take up The parts are now. in, the. position shown in Fig. 1 but with the coupling slack in the cable.

Now to cast; the anchor a -pullupon the cord 29 is efi'ected to shift the armsifland parts f carried thereby to the positions-shownby dotted lines in Fig. 1 with the coupling mechanism again connecting the arms 2d with the cheek pieces ll, provided this was. not done immediately. following deposit of the anchor .upon the deck. This movement of the sheave doubles the cable as shown by said dotted lines, the required slack .needed for this being'obtained by unreeling the winch. As the parts reach these 'positionsthe wedges will be automatically disengaged from the spring 24 owing to relative change in positionof the latching mechanism and consequent change in direction of pull of the cord 29upon the wedge actuator 36 and the dogs will enter the grooves .26. The winch now being started tozwind the cable force will be exerted upon the sheave 2i andthe dogs being engaged with the shoulders 21 will move both the. arms and the cheek pieces or housingand swing them into a-v'erticalpositionfrom which they will move by v gravity into the position shown in Fig. 2. .Slack in the cable caused by this downward movement will betaken up by movement of. the anchor into the water, more cable beingsupplied, ifrequired,

by reversing rotation'of the winch. Q

Cushions may be provided to receive the arm 8 as it reaches'its lowered position inhoisting or casting the anchor, or any suitable means may understood that the device shown is onlyillus- -trative and .thatthe invention may be carried out by other means and applied .to uses other than those above set out. a
